The imaging performance of segmented optical telescopes depends on the positional
assembly accuracy of segmented mirrors. In this paper, we present a novel method for …

For spatio-temporal and topologic analyses, vectorial information (carrying coordinate
values defined as point sets) gives better information than its raster (grid of pixels) …

The distribution area of carbonate rocks in Beijing is about 5071.44 km 2, accounting for
30.19% of the land area in Beijing. The distribution areas of bare, covered and buried …

Image-based line segment extraction plays an important role in a wide range of applications.
Traditional line segment extraction algorithms focus on the accuracy and efficiency, without …

The Hough transform (HT) is a widely used line extraction method to detect the boundary of
urban features. However, the HT has some problems, such as high computational costs and …

Vector data structure produces smaller file size than raster image because a raster image
needs space for all pixels while only point coordinates are stored in vector representation …

Aiming at the problem that high-resolution optical remote sensing image, lines are prone to
fracture, and a line segment optimization algorithm is proposed in this paper. Firstly, the line …
